Scientific Linux Security Update : kernel on SL3.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

A flaw was found in the handling of process death signals. This
allowed a local user to send arbitrary signals to the suid-process
executed by that user. A successful exploitation of this flaw depends
on the structure of the suid-program and its signal handling.
(CVE-2007-3848, Important)

A flaw was found in the IPv4 forwarding base. This allowed a local
user to cause a denial of service. (CVE-2007-2172, Important)

A flaw was found where a corrupted executable file could cause
cross-region memory mappings on Itanium systems. This allowed a local
user to cause a denial of service. (CVE-2006-4538, Moderate)

A flaw was found in the stack expansion when using the hugetlb kernel
on PowerPC systems. This allowed a local user to cause a denial of
service. (CVE-2007-3739, Moderate)

A flaw was found in the aacraid SCSI driver. This allowed a local user
to make ioctl calls to the driver that should be restricted to
privileged users. (CVE-2007-4308, Moderate)

As well, these updated packages fix the following bug :

- a bug in the TCP header prediction code may have caused
'TCP: Treason uncloaked!' messages to be logged. In
certain situations this may have lead to TCP connections
hanging or aborting.
